Saving preprocessed data in a raw MEG format

[Geoff Brookshire]

Hello,

I'm working on source localization of MEG ERPs, and have run into a
couple issues that I'm hoping someone will have some experience with.
I'm using MNE software to perform the localization, since Fieldtrip is
only able to do this on time-frequency data now.  The thing is that I've
already done pretty extensive preprocessing in Fieldtrip and so can't
afford to ditch that.  My hope is that I'll be able to output this
preprocessed data from Fieldtrip in a format that MNE can read.

I've seen people talking here recently about a similar issue, but that
thread ("Export EEG Data") seemed to deal very specifically with the
brainvision_eeg format.

I've been hoping to export the data as a .ds directory, as it was
originally saved.  MNE can convert CTF .ds directories to .fif (the
format it normally uses), but I don't think this is a possible output
format for ft_write_data.

Any ideas anyone has on how to proceed would be greatly appreciated!

Thanks,
Geoff Brookshire
